235/60/15 on front of duster?

if the 15x7 are 4.5” backspace you mentioned, you should have similar clearance as kerndog.

The 15x6.5 rallye’s are factory rims on mid-late 70’s B-bodies. Never been reproduced.

Good to know. Thanks for the info. Should I go straight for the 235’s with the 15x7 with 4.5” bs? That way I could still go with the Cooper tire.
